My New Low Restriction Performance Exhaust. A Better Illustration.

An update to a previous post on my exhaust system. In these pictures, you can more easily see how my new Y-PIPE exhaust pipe is greatly more advantageous than the old stock 180 degree U-turn interference flow factory exhaust pipe. Seeing the increased size and flow characteristics of the new exhaust system combined with the head exhaust ports being enlarged and port matched, you can see the improvement over stock is substantial. The truck is running so good, it has surpassed expectations. We will be taking our maiden, in state camp trip soon to see how well the truck handles the truck camper now with all the engine improvements. The improvements were focused to achieve a few goals. Improve cooling. Improve breathing, intake and exhaust. Improve electrical service with the 250 amp alternator. Improve load carrying with the 3 leaf front springs. Improve ground clearance gaining 4" height, front and rear. I still have the old Firestone air bags in the rear to trim or level the ride as necessary. I also rebuilt the AC system which will be a nice comfort at times for defrosting in the mountains, cooling in Arizona, and other places south. Over the last year, I've spent total $ 7116.60 on parts, mostly for this project but other items such as ignition coils, injectors, O2 and several other sensors. On tooling to do these projects, I spent $ 5004.51 over the course of the year. The single largest item is the HF Titanium 200 amp Unlimited multi-welder and related support products totaling $ 1799.51. Other items of note, Scanner code reader, $ 427.23, ARGON and MIXED GAS TANKS $ 572.26, and a couple other expensive tools, all of which will be used for many other projects. 

I'll have another update on performance and how all the repairs worked and held together. My only concern is the front right intake manifold coolant crossover where it connects to the head. Frod engineers chose to put one bolt to hold the coolant tube to the head in that location. There is a second bolt, cleverly, uselessly placed about 5 inches away on the far side of the #1 intake port, nothing between where it is really needed. I have devised a fix for that that does place more even pressure down on the tube to prevent the most common leak with these engines between the coolant tube and the #1 cylinder intake port. There are hundreds of videos on YouTube by people trying to fix this issue. Hate to say it, but my video on the topic is the only true fix for the problem. 

OK, back soon with the update.

We are seeeing this in different ways. 

Tow vehicle to me means hitches and equipment for towing. It can relate to the truck in relation to towing, but not necessarily the truck itself, rather as a unit. If a member of this group does this and wants to write about it, fine.

 I'm  writing about a truck and camper either separately or as a unit. Any work to my truck is in relation to improving carrying and hauling capacity, capability for the truck camper which can be similar to the needs of a trailer person, my information is intended for improving carrying a truck camper, similar to a tow vehicle, different purpose, not the same.

Really not sure why you don’t post this in the tow vehicle forum since it has almost everything to do with the vehicle itself and effectively nothing to do with a truck camper.
